Individualized Aerobic and High Intensity Training for Asthmatic Children (8)

March 18th, 2013

Moreover, the parents pointed out that their children were sometimes able to prevent acute asthmatic attacks by practicing relaxation and breathing exercises; the children were also described as being less anxious than previously. These observations were unlinked to the intensity of training. flovent inhaler

Time Course of Lung Function
We observed no significant differences between the two groups throughout the study.Effects of Aerobic Training
The Vo2max (ml.kg.min) was significantly higher (Fig 1) in the training group after aerobic training (p<0.001). At Vo2max, the training group showed a significantly higher Ve (VEmax) than control subjects (Fig 2, p<0.01). The improvement of VEmax occurred by increasing Vtbw and Vtbw/Ii (p<0.001), but f did not change.
At the same metabolic level (Table 3), which corresponds approximately to 85 percent of their initial Vo2max, the swimming group asthmatics exhibited higher VTBV/Ti after aerobic training (p<0.01).
Ventilatory threshold was increased in the training group (p intergroup <0.001 and p intragroup <0.01) by 20 percent after aerobic training.Maximal heart rate (HRmax) was increased (Fig 3, p intragroup <0.05) but the difference between the two groups after aerobic training was at the limit of significance (p<0.06). At the same time, we observed a significant maximal 02 pulse increase after aerobic training (p intragroup and intergroup <0.001).

Figure 1. Time course, between T0, T3 and T6 of maximal 02 uptake (Vo2max) and VTh in the swimming group (closed circles) and in the control group (open circles). The data are presented as mean ± SEM. Intergroup comparisons at each time (bottom of the figure): ft, p<0.01; ttt, p<0.001; NS, not statistically significant. Intragroup comparisons in the swimming group: **, p<0.01; ***, p<0.001; NS, not statistically significant.

Time course between T0, T3 and T6 of ventilation divided by weight (Vebw), respiratory frequency (f), tidal volume divided by weight (Vtbw), and mean inspiratory flow divided by weight (VTBVV/Ti), at maximal exercise, in the swimming group (closed circles) and in the control group (open circles). The data are reported as mean ± SEM. Intergroup comparisons at each time (bottom of the figure): t, p<0.05; ft, p<0.01; NS, not statistically significant. Intragroup comparisons in the swimming group: *, p<0.05; **, p<0.01; ***, p<0.001; NS, not statistically significant.

Figure 3. Time course between T0, T3 and T* of maximal heart rate and Os pulse in the training group (dosed circles) and in the control group (open circles). The data are expressed as mean ± SEM. Intergroup comparisons at each time (bottom of the figure): t, p<0.05; ttt, p<0.001; NS, not statistically significant. Intragroup comparisons in the swimming group: *, p<0.05; **, p<0.01; ***, p<0.001; NS, not statistically significant.
